Answer: The final temperature of the mixture will be
Explanation:
As we know that,
.................(1)
where,
q = heat absorbed or released
= mass of first sample of ethanol = 100 ml
= mass of second sample of ethanol = 300 ml
= final temperature = ?
= temperature of first sample of ethanol =
= temperature of second sample of ethanol =
= = specific heat of ethanol
Now put all the given values in equation (1), we get
Therefore, the final temperature of the mixture will be
Answer:
TRUE
Explanation:
Each electronic shell in an atom is composed of subshells, which are denoted by the symbol s, p, d and f. These subshells are represented by the principal quantum number (n) and the azimuthal quantum number (ℓ).
Each subshell can hold a fixed number of electrons, which is equal to (4ℓ + 2) electrons.
For, d subshell the value of ℓ = 2.
<u>Therefore, the maximum number of electrons that a d-orbital can hold = (4ℓ + 2) electrons = (4×2 + 2) electrons = 10 electrons.</u>
In geology and mineralogy, a mineral or mineral species is, broadly speaking, a solid chemical compound with a fairly well-defined chemical composition and a specific crystal structure, that occurs naturally in pure form.

Answer:
- Increasing the temperature: shifts the equilibrium to the products side (towards the right direction).
- Decreasing the temperature: shifts the equilibrium to the reactants (towards the left direction).
Explanation:
Le Châtelier's principle states that when there is an dynamic equilibrium, and this equilibrium is disturbed by an external factor, the equilibrium will be shifted in the direction that can cancel the effect of the external factor to reattain the equilibrium.
For the mentioned endothermic reaction can be represented as:
Co(H₂O)₆²⁺ + 4Cl⁻ + heat ⇌ CoCl₄²⁻ + 6H₂O.
In endothermic reactions: heat is a reactant for the forward reaction and a product for the reverse reaction.
So the effect of temperature on the equilibrium position is:
- Increasing the temperature:
Increasing the temperature leads to increasing the concentration of the reactants, so the equilibrium will be shifted to the products side (towards the right direction) to suppress the effect of increasing T.
- Decreasing the temperature:
Decreasing the temperature leads to decreasing the concentration of the reactants, so the equilibrium will be shifted to the reactants (towards the left direction) to suppress the effect of decreasing T.
Na3PO4*12H2O + BaCl2*2H2O = Ba3(PO4)2 + NaCl + H2O
add barium chloride to your Na3PO4.12H2O a white precipitate of Ba3(PO4)2 will be formed wrt salt(NaCl) and water(H20) if Na3PO4.12H2O. will be there.
